Key value for chemical safety assessment

Additional information

The Guidance on information requirements and chemical safety assessment, Chapter R.7C: Endpoint specific guidance (November 2014), section R. 7.11.6.3, Table R.7.11-2, page 145, specifies the information needed to waive the terrestrial studies based on soil hazard categories.

The log Pow of the registered substance is <3. Therefore, accumulation and persistence of the registered substance in soil and organisms is very unlikely. A PNEC soil was calculated using the aquatic PNEC and the equilibrium partitioning method. Based on these characteristics, the registered substance is not expected to cause adverse effects on terrestrial organisms and consequently terrestrial toxicity tests are not needed.

A read across chronic earthworm study is available but was not used for the risk assessment since the result calculated with EPM resulted in a more conservative value PNEC.
